This version can be pinned in stack with:concurrent-output-1.10.12@sha256:50e14131c486611055e2fa4f01a2ed03e63051e6d6707650f0a8f2f4ca618477,1665

Lets multiple threads and external processes concurrently output to the console, without it getting all garbled up.

Built on top of that is a way of defining multiple output regions, which are automatically laid out on the screen and can be individually updated by concurrent threads. Can be used for progress displays etc.
